a square central aperture to receive lsaid shaft. 'llie upper end of the shaft 27 above said valve is provided with a socket littin .29 that receives the ball '.30 on thc lower en of the. rod 19. By this arrangement, it will be evident that a movement of the lever 14 on its fulcruni will cause shaft 7 toslide vertically., and it willalso be evident that a rotation of said shaft will turn the valve 25 in its seat to open oi' close the port 14; 'l` he rotary motion of said shaft is not ii. mii-ted to the rod 1l), owing to the ball and socket connection between said parts.

'lravexsing one side f the valve 25 is a ehniinel 3 0 which when in the open position, as shown in Fig. 4, connects the channel .21 with the port 24 and permits the air to escape fronithe train pipe, effecting an ai'plcation of the brakes, as will be well un er- Vstood in the art. The closed position of the valve, which is its normal position, as shown in Fig. 3, maintains the air in the train pipe.l

Located at the side of the track is a suitable housing 31 prcforablysup ortcd-by the Seated in saicFhousin'g is a vertically movable contacting pin 32 having Aa flarii ca 33 on its up er end which embraces ie ss 34 of the ousing surrounding said pin, to exclude snow and water from said liousinfr. Located in the housin" 31 to reciprocatexlongitudinall is a slide plate 35 having a longitudinal s ot 36 with an inclined portion 37. The lower end of the contacting pin 32 is bifui'cated and stiaddles the plate 35, its bifureatedonds beine joined by a transverse pin 38 which passes through said Connected to one end of the' slotted plate is a rod 39 which leads to a semaphore or other signaling apparatus, not shown, the arrangement being such that the o eration of the signaling device will actuate t e plate 35 in the following manner When the signal is. set at danger, 'the plate 35 will be moved longitudinally to cause the in 38 to ride u the inclined portion 27 of t e slot in said p ate thereby projectiniy the contactor from the housing, as shown by dotted lines in Fig. 1. A reverse movement of said plate will restore said contactar to its normal position.

The operation of the device as herein shown, is as follows 'lhe setting of the signal at danger will raise the contacting in to the dotted position shown in Fi 1. ould the engine-man obey the signa and reduce the speed of his train so as to place it under immediate control, the train will be allowed to slowly pass the signal at dangerwithout o ratin the automatic stopping device. S ould t e engine-man however fail t-o see the signal or to obey it, and should the train upon reaching the signal be running at regular or l1" h speed, shaft 4 through its connec- 'tion wit the axle will be. revolved so rapidly as to cause the balls 'of the governor, by centrifugal force, to swing outwardly and raise the collar l2, as shown by dotted lines in Figs. 1 and 2, at the same time liftin the -tlie valve 25 and open the port 24, permitting the air to escape from the train ipe and making an a plication of the bra es. -As the speed of t e train is reduced the balls of the governor will fall and the weight 13 will restore the parts to their normal position.

It will be evident that with the train moving at a slow rate of speed, the centrifugal operate the lever 14 and depress the arm 18 o the shaft 27 such distance as to cause it to engage. the contacting pin. By this arran eforce of the governors will not be sufficient to. t

ment a train is enabled to4 run past t e dancer signal when under control and is also ena led to back when required for switching or for other purposes, without actuating theautomatic stopping device, an arrangement.

of material importance Where the traffic is heavy, as the ordinary movementof the 4train; is notd interfered with, and delaysincident.v

to the. undesired application on long trains, are obviated..

Having thus fully set forth my invention,4 what I i: aim as new and desire to secure by r Letters Patent, isz- A.
